This invention relates to :1 device for measuring liquids, and consistsof a pair of tilting tanks which are normally held level lavconuterweights, but which independently till. when liquid deposited inthem reaches a certain weight, the tanks having means for withdrawingthe liquid when we tilting takes place.

-The invention relates to a. weigher of this type which is accurate, dueto an improved regulating means on the inlet pipe for alternatelydirecting the liquid into one tank and then the other. the directingmeans being operated by the tanks alternately as they. tilt. Theregulating means is fixed and has fixed outlets, the directing of theliquid "being due to an interior construction of e valve to which theoutlets are connected.

A furtherohjeetof the invention is the provision of a regulating meanswhich pro vides for a maximum flow when'the liquid is first directedinto the tank, and for :1

slower flow or one with less volume as the tank becomes fuller.

The invention is illustrated in the accompanying drawings, in whichFigure l is a side view of the improved liquid measuring device. Fig. 2is a front view of the device shown in Fig. 1. Fig. 3- is .a viewshowing one-half in section and one'hall' in ele ation of the valveuscdin the construction shown in Fig. l. Fig. l is a side view of the topportion of the measuring device of a modified form. Fig. 5. is a frontview of the apparatus shown in Fig. 4. and Fig. 6 is a sectional view ofthe valve used in the construction shown in Figs. 4 and 5.

Any suitable frame is employed having a base 10 and standards 11 onwhich are mounted the knife-edges 12 of the tanks 13a and 14. xThetanksare adapted to swing on the knife-edges and are mounted the they swingindependently. The tanks'have eounterweights 15, the counterweights hemg adapted to hold them in their normal positions. that the weights holdthe M from tilting when they are, came-v.

tank one-he right in Fig. normal position, and it v." Fig. I that it'isr" p on the rea. T he tank 13in tilted and rests on I horizonial or evenposition, but when u; is poured into the tank. when it arrives at a,certain height; the tank is tilted by rea of this weight overcoming thecountervi eight l5. and the tank when tilted is emptied by the siphonpipe 18 which projects ends within the tanht,

from its iront and e" preferably in the depressed poriion l9, wheeoy thetank is emptied even aller the weight of the liquid in it has-beenreduced and the tank again becomes horizontal. The middle standard 11has a frame 20 mounted thereon. On the front end of the frame 20 is avalve .21 which is shown more in detail in Fig.3. The valve 21 l1i1S.21casing. the topof the casinghaving an inlet -23 adapted to be connectedlo a suitable inlet pipe which is not shown in the drawings. The valvecasing is provided with spouts 24 which are fixed when the casingis inplace .soihat there is-iuo, tilting of the spouts and the direction andforce of the liquid .are m not varied through any difference in itsangle or in the angle of liowof the liquid.

The casingis provided with a suitable.- lining 25, and withiuthe liningis arranged a valve ring 26 which is. cut away as at E37 so llmatthesolid portion of the ring extends .su-fiicicntly to shut Millie liqul'from the spouts aliernately when-the ring is swung or partly turned bythe rod 28 which DIO- jcclfs from the'liack of the valve. The end wall29 iscul' away atflll to receive a stop-bolt tlL-the st-op-boltthuslimitingt-he swing of the valve ring 94 The rod 28 extends ,lhrough thebracket 32 shown in l ig. l and is connected to a suitable counter ill,which .mcords-the mun-her of tilts to which the rod .is subjected, andthus records the amount of liquid that ispassed through the weigher. Therod rocked by the pins 3% which project .from opposite sides of therod28 and are secured thereto by suitable clamp 3.3. it will thus beseenihet when. the liquid IOU is flowing from the inlet pipe throu h oneof the fixed spouts it will fill a tan and when the tank tilts, the backedge of the tank engages the pin 34 on that side, the pinnormallybeingaclear of the edge of the tank so that the tank is inmotion before it en-' gages the pin and thus is not retarded in itsaction. The tank by this'engagement with the pin rocks the rod 28, thevalve rin 26 is turned with it, and the liquid is. shut oiiifrom thetilted tank-and is directed into the tank on the opposite sidewhichinturn becomes filled while the tank that istilted is being emptiedthrough its siphon pipe 18.

. .In Figs. .4, 5 and 6 I show a modified form in which a supplementalregulating attachment is supplied to amodified form of Valve which hasfor its object to permit a maxi the-valve 36 isof' a modified formofconstruction which is shown in section in Fig. 6,

The valve has a casing 37. with. an inlet 38, and at oneend it isprovided with a cap 39 having astufiing box 40 through which protjects.a'rod 41 on which issecured a valve ring 42 which is cut away at 43 tohave-the ing -42" on each side. adapted'toshut off alternately the majorporside edges of the cut away portion engage a stop bolt 44 to limit theturning of the valve ring. The valve ring. 42 has an open The valve ringis tion of the inner end of the outlet of the spouts 45, that is, thespout is shut off by the ring 12 for the major portion of its intakeend. This shut-off takes place by means of arms '46 which are engagedalternately by arms 47, the arms 46 being fastened to a suitable boss48' and provided with a weight 49 which completes the swinging of therod 1 41. when the weight 49 goes over the center. The arms 47 are bentto clear the spouts 45 and are fastened to the sleeves 50, the sleeves50 being mounted on the stems 51, the stems 51 being provided withfloats 52 at their lower ends, the stems also being attached to therocking arms 53, the rocking arms being mounted on the bracket 54 andbeing adapted to hold the stems vertical. It will thus be seen that whenthe liquid in a tank rises up to a certain point, the float 52, throughits stem and its arm i7, litts an arm -16 on that side of the valveuntil the weight 4:9 goes over the center, when the weight then carriesthe valve ring 26 to a closed position so that the major portion of theliquid is shut off from the tank. The liquid, however, still flowsthrough a small opening 55 which can be shut oil by the valve ring 56fastened to the rod 28 passing through the stufling-box 57 of the cap 58and being limited in its movement by the stop-bolt 31. The rod 28 inthis instance is operated as described in Figs. 1 and 2, this operationtaking place when a filled tank is tilted, whereby when the supply isentirely cut off there is a relatively small amount of liquid being fedto the tank when it tilts. v i This invention is simple in its operationand; is positive, and itisan improvement which provides for a moreaccurate weighing of the liquid by reason of they graduate amounts thatare fed to the tanks .in their filling, and also by reason of the fixedcasing and the outlets which provide for positive opening and shuttingof the valve.

Havingthus described my invention, what I claim is: I I i l 11A liquidweigher consisting'of a pair of tilting tanks, the tanks beingunbalanced and having means for emptying them when extending to bothtanks, a rocking rod extending from the valve casing, arms on the I rodand in the path of the tanks when they 'tilt,'and a valve mechanism inthe casing and acting to alternately closethe spouts as the rod isrocked.
